نقو في عملنا بإيجاد الجيوديزيات في زمكان الثقب الأسود المشحون في سياق ثقالة
قوس قزح و مقارنتها بمثيلاتها في النسبية العامة الكلاسيكية. معلوم أن الجسيمات في
زمكان الثقب الأسود تتحرك على جيوديزيات يمكن إيجادها من خلال كتابة المعادلات
الحركيّة الموافقة. تسعى الدراسات الحديثة إلى إيجاد مقاربات للنسبية العامة الكلاسيكيّة
بهدف حل مسألة الشذوذيات؛ تلك النقاط التي تنهار عندها القوانين الفيزيائية لتغدوَ
المعادلاتُ الرياضياتية عديمةَ المعنى عندها، إذ أنها توافِق نقاطاً لا نهائية التقوس. نجد
في بحثنا أن ثقالة قوس قزح لوحدها لا تغيّر في البنية الجيوديزية للثقب الأسود
المشحون؛ أي أن مسار الجسيمات الصادرة عن الثقب أو التي تتجه نحوه لا يتغير.
We find the geodesics in spacetime of charged black hole in
context of rainbow gravity and then we compare them with ones in
classical general relativity. It is known that the particles in
spacetime of black hole move on geodesics which we can find by
writing the equations of motion. Present studies aim to discover
approaches to classical general relativity for solving the
singularities problem, the points where law of physics destroy at
and then the mathematical equations become incorrect because they
are points whose curvature is infinity. We find in our work that the
rainbow gravity, its own, does not change the geodesic structure of
charged black hole and so neither ingoing nor outgoing particle
trajectory will change.

In this research paper, we study geodesic mappings
of gravitation fields . The mapping listed are considered,
on the one hand, a generalization of aftomorfizm of
movement and harmonic mappings, and on the other
hand the practical mappings in the theory of relativity .
